1st rectangle:
width: 2.48cm
length: 4.96
2nd rectangle:
width: 4.96 (equals to the length of the 1st rectangle)
area: 9.92
length: 9.92/4.96 = 2
Because the nonagon is regular, the angles are equal. Nona means nine. The total of the measures of the interior angles of any polygon is (n-2)180. Use this formula to find the measure of one interior angle.
(9-2)180
7*180=1260. Divide by 9 to get the measure of one angle.
1260/9=140
The answer is 140 :)
Answer:
Step-by-step explanation:
